Vertical compression forming process for ceramic blanks for bathrooms

Abstract

The invention belongs to the technical field of ceramic forming, and particularly relates to forming process for ceramic blanks for bathrooms. The forming process comprises steps that 1, forming materials are prepared according to proportion and mixed uniformly, 2, forming mud of a blank is refined and uniformly mixed, and moisture content of the mud is controlled below 30%, 3, forming mud in corresponding weight is taken according to the weight of the formed blank, 4, the forming mud is placed in a forming mold, and the mold is squeezed so that the blank is formed, and 5, by the aid of the forming mold, air is blown into a combined part of the forming mold and the blank, so that the blank is separated from the forming mold and is produced. The vertical compression forming process for ceramic blanks for bathroom is fast in forming speed, high in manufacturing efficiency, low in mold cost and small in occupied area, and the blank is compact sufficiently.

Description

technical field [0001] The invention belongs to the technical field of ceramic molding, and in particular relates to a molding process of a sanitary ceramic blank. Background technique [0002] The production process of sanitary ceramics generally includes the following steps. First, prepare slurry, then use the slurry to make blanks, then glaze the blanks, and finally complete the product through the sintering step. [0003] Most of the existing sanitary ceramic blanks are made by the traditional grouting molding process, and the hollow grouting process and the solid grouting process are selected according to the shape of the sanitary ceramic blanks: that is, for the usual small opening blanks, it is difficult to remove the inner core, The hollow grouting process is used to make the shape; for the blanks with large openings or small openings that can be spliced, it is easy to take out the inner core, and the solid grouting process is used. [0004] For blanks with large op...

AI Technical Summary

Problems solved by technology

[0005]1. The solid grouting process takes a long time to form, usually more than 4 hours before demoulding;

[0006]2. The density of the blank obtained by the solid grouting process is not uniform enough. Usually, the part of the mold with good water absorption performance is relatively dense, and the part with insufficient water absorption performance , the blank is not dense enough;

[0007]3. In the solid grouting process, there may be bubble defects in the blank due to the presence of air bubbles in the grout, and the compactness is not good enough;

[0008]4. After the mold is demoulded, it needs to be dried before it can be used again, resulting in low production efficiency of the blank;

[0009]5. Due to the low molding efficiency of the solid grouting molding process, a large number of molds usually need to be made for large-scale production, which not only increases the production cost, but also takes up a lot of the area of
